A Japanese dialect spoken in the western parts of Hiroshima Prefecture. Usually considered the stereotypical Yakuza dialect.
Heavily features the usage of じゃ (ja) as copula instead of だ (da) in Standard Japanese. Prefers のう (nou) as the sentence-final emphatic particle (instead of Standard Japanese "yo" or "ne"), and shortens から (kara) to け ("ke", often elongated to "kee"). "Jakee" will also pop up in place of the standard "dakara" (this can sometimes be deceptive as it can also have a different nuance).
Female speakers will often use "uchi" as a first-person 'pronoun'. Male speakers will sometimes use "washi".
"Gaijin" foreigner characters are sometimes also given this accent. The usual justification is almost invariably "this character learned Japanese by watching Yakuza films".
On Danbooru, the Hiroshima dialect is sometimes adapted into a West Country accent.
